SODA-WATER DRAFT ARM AND FAUCET,

To all whom it may concern: I

Be it known that'I, JOSEPH A. MCCORMICK,

a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new, use ful, and Improved Soda-Water Draft Arm and Faucet, of which the following is a full, clear, concise, and exact description, such as will enable those skilled in the art to make and use the same.

My invention relates to improvements in faucets and has special reference to soda water draft faucets.

The object of my invention is to provide a faucet whereby when the faucet is opened the initial movement of the handle shall result in a smooth stream of solid liquid at low pressure for quickly drawing the required quantity, and the further movement of the handle shall result in the projection of a small stream of the liquid at high velocity for thoroughly mixing the previously drawn liquid and producing the desired efi'ervescence.

My invention consists in a faucet of the kind described, provided with a valve controlled chamber connected to a supply of the liquid and provided with two delivery passages of respectively large and small area and'means whereby when the valve is first opened the delivery is through the large passage and wherein a further movement of the operating-handle results in the closing of the large delivery passage','causing the liquid to be delivered throughthe small passage.

My invention also consists in a soda water faucet having a large and a small delivery passage, a valve controlling the flow of liquid to both of said passages and means for closing the large passage after the valve has been opened for shutting off the flow through the large passage and limiting the and parts whereby I am enabled to attain Specification of Letters Patent.

tion, ofa draft arm and faucet portraying a preferred embodiment of my invention; Fig. 2 is a central vertical sectional view of the faucet on the line 2-2 of Fig.1;

Fig. 3 is a detail horizontal section on the line 33 of Fig. 1; and

Fig. 4 is a plate.

In the operation of drawing a. glass of soda waterit is desirable to draw the glass three-quarters or seven-eighths full of the water without disturbing it to any appreciable extent, and thus preventing the efl'er vescence thereof, then to project a small stream of the water at high velocity into the glass to effect-a thorough mixing of the contents and the violent efi'ervescence of the water.

While faucets have been produced which result in an approximation of the result dea hollow stem 10 adapted for mounting on and connecting to a soda water fountain as by the threaded pipe nipple '11. The stem carries the faucet proper 12 at its outer end.

I preferably removably mount the faucet on the stem by the threaded connection 13. The stem and the faucet are provided with a central passage 14 for the flow of the liquid from the supply. The faucetshell or casing Patented Feb. 25, 1919.

IIED s'rATns PATENT OFFICE.

perspective view of the cam 15 is rigid with the stem and stationary.

Within the casing 15 I provide a relatively large central valve chamber 16 in communication .with the supply passage 14: and provided with a valve seat 17 at its lower end,

surrounding a central discharge passage 18, The chamber 16 opens through the upper end of. the'casing 15' and I close the upper end with a screw plug 19. WVithin the cham-;

ber 16 I provide a valve 20 for closing the discharge passage 18. enlarged head 20, provided with a packing Washer or disk 21 on its lower end secured This valve has an to the body of'the valve by a central screw 22. I yieldingly hold the valve upon its seat by a helical compression spring 23 Which surrounds a stem 24, upstandingfrom the valve20, and finds a seat for its upper end within the plug 19.

The head 25 of the screw 22 is relatively thick and depends with-in thepassage 18 and I make it conical, as shown, so that it will tend to center the valve 20 should there be any tendency for. the same to beforced side- .W1se.

The passage18 is relatively short and terminates in. an enlargedinozzle or outlet 26 1 in thelower endofthe. body 15.'

For lifting the valve2O I provide a faucet handle ,or lever 27, which normally extends centrally above the faucet body. Its lower end is forked to straddle. the faucet body.

The.ends:28..of theforkedhandle are perfo- 7 rated to receive pivotpins 29. for pivotally mit s the handle to move up and down on mountingthe handle. on the body. 7 These pins have cylindrical inner ends '30 which slidingly fit within vertical guide slots 31.

in the sides of the faucet body, which per the. body. v I make the lower end of the body 4O'eyl1ndrical and mount thereon a nozzle extension 41, ,which I provide with diametrically. disposed arms 42 projecting upward from its upper end and adapted toloe arranged be tween the. arms 28 of the handle and the body ofthefaucet. These arms 42are provided with ,threadediopenings 43 to receive and retain thepivot pins 29, which are correspondingly threaded for mounting therein.

The. nozzle extension 41 terminates at its lower end. in a discharge openingof relatively large. size, and wh1ch' is slightly contracted at its extreme. end, being conical in valve 45 relatively. to the bar 46 and I so proportion the several. parts that the valve 45 willseatt-o close the passage 18 upon being lifted v about one eighth of an inch.

For liftingthe valve 20 I provide a central; stem 50, its lower end. secured in the valve. 45 andlong enough to extendup into the passage 18' and contact with the lower end of, the screw head25. Thisstem has a shoulder 41. which serves to clamp the packing, disk .52. uponthe valve 45.

For lifting the nozzle extension 41 and thus throughthe valve 45 and the stem 50, lifting the valve 20 to open it, I provide a cam surface 53 1 in a cam plate- 54-, mounted on the top f theclosii ig'plug 1Q" an l immediately below the handle 27. I provide the cam surfaces'5-3-ii1 the se arate late 54 which is carried by the body of the faucet,

so that'I can make the cam plate of a different,a-nd.if. desiredtof a harder metal than the body of the faucet. I preferably make the cam plate 54 in thefor-in ofkadisk and.

I provide, a; shallow socket 545 having 21. peripheralupstanding vflange '54 for receiving and'retainingahe.cam plate ordisk54. This separation of the cam plate from-the-top; of the faucet. perm-its of: easier manufacture and assem'bly as-theicam plateis self alining; withsrespect, to the roller; This cam surface:

mal position of the-handle the roller 55 con.- tacts with thelower part thereof. The handle 27 can swing'back and forth over the body. of the faucet on the pivots 29 and any movement: from the central normallpositi on Wlll cause the roller 55 totravel up. the iii-- elined surface; ofthencam and lift the handle, the nozzle extension, and-in consequence the valve 20,: thus utting the delivery passages 18 and26, in direct communication with the central valve chamber 16 It will be clear that the farther the handle-27 swungover'within the limits of'the device. the higher the partswill be lifted, until finally thevalve 45 will close the lower end of the passage 18'. As soon as the valve 20 is lifted/from its seat, thewater is free to flow through the passage 18, around the valve 45, through the passage 26 and the discharge nozzle. The passage 26- and the discharge nozzle are so large in relation to the annular space within the passage 18 around the stem 50, that the initial high pressure of the water is eliminated and'the water flows from the'nozzle in a smooth, solid stream, at low velocity.

In the operation of the device, when the valve is lifted far enough to close the lower end of the-passage-lS, the free flowing of the liquid in a large stream is-t'erminated- This point is within the control of the opera- The. roller. '55

The cam. surface 53 is inclined upwardly bothrearwardlyand forwardly from the center of the faucet andin the nor-- tor, for he merely has to move the handle 27 far enough to effect the closing of the lower end of the passage 18;

Having filled a glass three-quarters or seven-eighths full of the water in a quiet state,it is now desired, as explained hereinbefore, to violently agitate the liquid and thus cause itsrapid effervescence. To accomplish this purpose it is desired to provide a small stream of the liquid projected at high velocity, for which a small central discharge passage 57 is provided, extending through the lower end of the stem 47 and communicating at its upper end with the threaded opening which receivesthe lower end of the stem 50, and I provide a central passage 58, extending from the lower end of the stem 50 and terminating adjacent to the upper end of the stem in lateral openings 59, whereby whenthe valve 4:5 has closed the lower end of the passage 18, the water will be forced at high velocity through the lateral passages 59, the central passage 58 and the small delivery passage 57,

I have thus provided two passages for the water from the valve chamber 16, one around the valve 45, which is of relatively large area and is successivly enlarged in area from its beginning to substantially its delivery end,"

causes the water to be projected in a fine needle-like stream from the discharge pas-- sage 57, under substantially the initial pressure of the water, thus causing the efficient mixing and effervescence of the previously drawn water.

On account of the relatively high pressure,

of the supply of soda-water the main valve 20 is held to its seat with relatively great force, but by means of the multiplied leverage which I have provided, viz, the cooperating cam parts andthe swinging lever 27 the operator is enabled to readily and easily open the valve 20 against the pressure of the soda-water in the valve'chamber 16. Once the valve is open it can be easily raised, when desired to close the lower end of the passage 18, but the leverage is such that even with the tendency of the closing of the lower end of the passage 18 to increase the pressure within the faucet, the operator is easily enabled to hold the valve 45 closed andthusproduce the small stream oflwater of high velocity, which is desired.

Preferably I provide a relatively large f delivery passage.

ball on the free end of the handle 16m 27 and I secure the ball upon the lever by means of a threaded stein 6land a flange nut 62, 4

providing the end of-the lever with a spherical socket 63 in which to seat the ball.

It is sometimes desirable to reduce the area of the supply passage 14 and for this purpose I provide a screw plug or-pin 64', Y

mounted in a threaded opening 65, provided in the body of the faucet and having its inner end 66 projecting into the passage 1 44. I provide a recess 67 in theinner wall of the passage 14L to receive the end 66 of the pin 64;, the recess 67 being slightly larger than the end of the pin, which prevents a complete shutting off of the passage 14. I provide the outer end of the pin 64: with a screw driver slot 68 for effecting this adjustment, and to prevent the escape of liquid around the pin through the opening 65, 1 provide a' packing nut 69 and packing 70 surrounding the stem.

As many modifications of my invention will readily suggest themselves to one skilled in the art, I do not confine or limit my invention to the specific structure herein shown and described, except within the limits of the appended claims.
